the predetermined value, while on the other hand, if the transformers -3 and 7 are adjusted to give the desired voltage in the incandescent circuit --5- when the load in the arc circuit is on, then, when such load is thrown off it will cause a rise of voltage in the circuits .1 and 5 in excess of the predetermined value. This, of course, results in poor service in the translating devices in the circuit 5 and in order to overcome this, and to maintain a practically uniform ,vol-

tage value in the circuits '1 and -5 I' Shave introduced into the circuit 1 a shunt transformer l 2 and a series transformer l3, and have also introduced into the are circuit 4t the winding of a solenoid -14.

The primary winding of the transformer -12 is connected across the circuit -l and the opposite ends of its secondary winding are connected by wires 15 and 15-- to' a pair of terminals o16 of an electric switch -S. This switch is provided with an additional pair of terminals 17-, one of which is electrically connected by a wire -l8 to an intermediate point substantially midway between the ends of the secondary winding of the transformer- 12 while the other terminal is electrically connected by a wire -18 to the end of said secondary winding to which the wire 15- is connected. The switch -S is also provided with a pair of movable contact arms -20- which are connected to the plunger 14 through the medium of an arm 21 and plunger rod 22, the arm ---21- being provided with a slot 23 to receive a pin '-24 on the lower end of the rod 22, to permit the plunger to move freely a limited distance, before actuating the switch The switch arms -20 are normally in-electrical contact with the lower terminals -l7, bemg forced to this position by the gravity of the solenoid plunger, when said solenoid is de-energized by opening the arc lamp circuit, said switch arms being also electrically connected by wires 25 and -25 to the terminal ends of the primary winding of the series transformer --13, and, therefore, this primary winding is normally in electrical connection with the low voltage or secondary winding of trans It will be observed that the connections of the secondary win ling of the transformer -12 with the lower and upper terminals of the switch are reversed so as to reverse the voltage impressed on the series transformer -13- when the switch is operated.

When the load in the circuit 1 is cut out, thereby (la-energizing the solenoid '14.allowing the switch to close the circuit through the terminals 17, a portion of the voltage, in this instance substantially half, in thesec'ondary winding of the transformer 12 is thrown into the primary winding of the series transformer 13 to oppose the flow of the current in the circuit -l-, and thereby cuts down its voltage by an, amount corresponding approximately to one third the rise of voltage caused by cutting out the load. On the other hand, when the load in the arc circuit 4 is thrown on thereby energizing the solenoid 14-, the switch is operated to break contact with the terminals l7 and to close the circuit through the terminals *1 6 thereb y adding the full voltage of the secondary winding of the winding transformer 12 through the primary of the serif-s transformer 3- to the circuit 1 to compensate for approximately two thirds of the drop of voltage in the system caused by throwing on such load. For example, assuming that the transformer 13 is adjusted with a one to one transformation ratio, and that the transformer 3 is'adjusted to give 2300 volts at no load in the circuit .-1-, and that the transformer 12 is connected to deliver .200 volts to the terminals 1 6 and volts to the terminals -17, then, whenthe arc circuit 4* is thrown'on causing a drop of 300 volts in the transformer 3-- audt'c-ircuit l-, and also energizing the solenoid -l4-, the plunger of said solenoid is instantly drawn upwardly and operates the switch -S- to open' the circuit at the terminals 17 and to close the circuit throu h the terminals 16-. Approximately tie full 200 volts is thereby thrown into the primary. winding of the series transforn'ier 13 and added to the circuit '1- to compensate partially for the drop of voltage caused by throwing on the arc circuit, and to bring the voltage back to amnoximatel 2200 in the circuit -l-. On the other land, when the load in the arc circuit is thrown oil by opening the switch -S the solenoid 14- is de-energized allowing its plunger to drop by gravity, which in turn operates the switch S to throw the arms -20- out of contact with the terminals '16- and into contact with the terminals 17-, thus throwing a reverse voltage of approximately 100 volts from the secondary of the transformer 12 into the primary of the transformer 13-- to oppose the voltage in the circuit 1- thereby lowering it to approximately 2200 volts. By this means, ll am enabled to maintain a practically uniform voltage of 2200 in the circuit 1 and a proportionate voltage in other parts of the system, as the incamlcscent circuit 5 deriving current therefrom; and it is clearly evident that this regulator may be used in other relations than that in a lighting system and that the voltage may he raised. or lowered any amount desired, or, the same operation carried out in any circuit of any desired voltage by making due provision or adjustment l i l l l l l 0" transformers, solenoids and switches. y i

The series transformer 1 3- may, in y some instances, be omitted, as in circuits of i comparatively low voltage and amperage, l the wires -25- and 25-' then being cohl nected to the terminals -26 and 20, where one side of the circuit -1- has been out or broken as in Fig. 3. The double co l series transformer 13 may also be replaced by a single coil or an mite-transformer if desired, (Fig. 2.)

It is also evident that the regulator may as used in connection with circuits of any number of phases by providing a suitable number What I. claim is:
